Embodiment 1

[0036] Embodiment one: see figure 1 , 2, 7, 8, a kind of acid mixing device, a plurality of acid tanks 2 for respectively storing different acid liquids are arranged above the mixed acid mixing room 3; The liquid inlet pipe 26; the upper end of the combined liquid inlet pipe 26 is connected to the acid tank 2, and the lower end is connected to the mixed acid mixing chamber 3 through a pipeline after the lower end is connected to each other; 261 intervals are arranged to form separated first flow passages 262; the first flow passages 262 corresponding to different confluence liquid inlet pipes 26 communicate with each other at the lower end of the confluence liquid inlet pipes 26, so that different acid liquids meet in a separated state; The guide tube 263 passes through the intersection of the inner tubes 261 corresponding to each other, and communicates with the first flow channel 262 respectively, so that the pre-mixed acid liquid flows into the mixed acid mixing chamber th...

Embodiment 2

[0037] Embodiment two: see Figures 3 to 8 , an acid mixing device, a plurality of acid cabins 2 for storing different acid solutions are arranged above the acid mixing room 3; a homogenizing device 6 is also arranged between the acid mixing room 3 and the acid cabin 2; The homogenizing device 6 includes a rotating body 61 rotating horizontally; the upper end surface of the rotating body 61 is a bowl-shaped distributing surface 611; the distributing surface 611 is radially distributed with a plurality of mutually separated second The flow channel 612, the second flow channel 612 is respectively defined by the heat conduction sheet 613 fixed on the distribution surface 611; the acid tank 2 guides the acid liquid to the rotating distribution surface 611 through a combined liquid inlet pipe 26 respectively In the middle part, the acid liquid is pre-mixed in the middle part of the distribution surface 611, and then flows out from the outer ring of the distribution surface 611 alon...

Abstract

The invention relates to an acid mixing method and an acid mixing device thereof. The method enables different acid solutions to be separated into multiple small portions before entering the acid mixing mixing chamber, and the different acid liquids are mixed between small portions in the separated state. The acid mixing device solves the shortcomings of the existing acid mixing device such as single structure, difficult operation, slow start, etc., and can realize direct mixing between concentrated acids. It absorbs the energy and heat mixed with concentrated acid to avoid danger, and it has high efficiency and fast speed, which is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of acid preparation, in particular to an acid mixing method and an acid mixing device. Background technique [0002] In recent years, my country's chemical production field has advanced by leaps and bounds, and the functions and requirements for acid mixing equipment have become higher and higher. Only equipment with a single acid mixing function cannot meet the various needs of its field and industry for acid preparation. The existing acid mixing method In order to dilute the concentrated acid and mix the acid, the water in the acid can be evaporated according to the need to increase the concentration again after the acid mixing is completed. This method has many steps, cumbersome operation and high cost. A quick way is to directly mix the concentrated acid to save the dilution and re-concentration process, but if the concentrated acid is mixed directly, it will easily cause a large amount of heat release, w...
